Connecting device for cords

ABSTRACT

The invention contents cord tying-up connecting device consisting of the first part ( 1 ) provided with a groove. One end of the first part is provided with an entering end the second part ( 2 ) is provided with a cam for connection with the second part ( 2 ) is provided with a cam for connection with the second part ( 2 ) formed by a hollow body provided with a bilaterally coincident cam. The thrid part ( 3 ) is provided with a through-hole and a shoulder towards the second part ( 2 ).

TECHNICAL FIELD

[0001] The technics solution concerns heald and cord tying-up conectingdevice applicable for all tying-up types.

BACKGROUND ART

[0002] For heald and cord tying-up connection there is used so far acoupling with polyolefin injection which enables only an unidirectionalconnection securing. There has been checked in effect that this securingis unprofitable as a disconnection in case of a return motion or buffingof adjoining couplings during weaving car occur. The used material ofthis connection does not guarantee the required frictional resistance.

DISCLOSURE OF INVENTION

[0003] The above-mentioned deficiences have been removed by the healdand cord tying-up connecting device in accordance with this technicalsolution, the substance of which consists of three parts. The first partis provided with a groove which enables its putting on the heald andconsequently a motion along the heald. One end of the first part isprovided with an entering end, another with a cam for connection withthe second part. The second part is formed by a hollow body with abilaterally congruent cam. The third part coincides in form with thefirst part and has, in addition, a through-hole for the cord tyingdevice and a shoulder towards the second part for a fixed bilateralclosing of the complete connection.

[0004] The device in accordance with this technical solution isuniversal and can be used in practice for all types of tying-up. Itsmost important advantage is that all parts are takable independentlywhich has not been known so far with any device for the given purpose. Abilateral securing connection between heald and cord tying device hasnot been solved anywhere to date as well. All parts being made of ahigh-resistant rub-proof plastic, the new product has a long servicelife even with a high speed of the weaving machine. A furthersubstantial advantage of this device is saving of two operations whichincreases productiveness and reduces laboriousness.

BRIEF DESCRIPTION OF DRAWINGS

[0005] The technical solution is further more detailed explained bymeans of a drawing where FIG. 1 illustrates a device when all threeparts are connected and both the heald and cord tying-up device arefixed, FIG. 2 illustrates the first part provided with a groove, FIG. 3is a hollow body with a bilaterally congruent cam and FIG. 4 illustratesthe third part with a through-hole.

MODE FOR CARRYING OUT THE INVENTION

[0006] The device in accordance with the figure consists of three parts.The first part is provided with a groove which enables to put it on theheald 5. One end of the first part 1 is provided with an entering endand another with a cam. The second part 2 is formed by a hollow bodywith a bilaterally congruent cam. The third part 3 coincides in formwith the first part 1 and has, in addition, a through-hole for the cordtying-up 4 and a shoulder towards the second part 2.

[0007] The device according to the technical solution is operated insuch a way that the first part 1 having been put on the heald 5 isconnected with the cap second part 2 yet before levelling in phase ofpreparation. In this way a sliding motion along the heald 5 is enabled.During the assembly the third part 3 is slided on the cord tying-updevice 4. The cord tying-up device 4 having been passed through theheald's 5 eye and alignement into the right levelling position, thecord's remnant is cut off. Owing to the semi-assemblys slliping fromparts 1 and 2 upwards, the heald 5 and the cord tying-up device 4 in thesecond part 2 are firmly clamped which prevents from picking-up orslippage of the cord tying-up device 4 in the heald 5. A motion of thethird part 3 towards the second part 2 causes a perfect camming of thewhole connection with a bilateral counter-motion locking.

1. Heald (5) and cord tying-up connecting device (4) designated so thatit consists of the first part (1) provided with a groove, one end of thefirst part (1) being provided with an entering end of the first part (1)with a cam, by means of which it is interconnected with the second part(2) formed by a hollow body provided with a bilaterally coincident cam,meanwhile the third part (3) is provided with a through-hole and ashoulder towards the second part (2).
